DUMPlNe-WAGON.

SPECIFICATION forming part of Letters Patent N0. 671,627, dated April 9,1901.

Application filed lloveinberZ, 1900. Serial No. 383048. (No model.)

To all weom'it may concern,.-

Be it known that I, EARL PHILBUEN LE GORE, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented a new and useful Dumping-Vagon, ofVwhich the following is a specification.

This invention relates to dumping-wagons, and has for its objects toprovide improved means for elevating the body of a wagon from therunning-gear thereof and for tilting said body, so as to dump or slidethe contents thereof out through the rear end of the body. It is alsodesigned to arrange the elevating and tilting mechanism, so that it maybe applied to any ordinary wagon and to arrange the same formanipulation by a single operator, and, finally, to provide for a slightadditional adjustable elevation of the rear end of the wagon-body, so asto vary the inclination thereof at different elevations to accommodatethe discharge to different circumstances.

With these and other objects in View the presentinvention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings,and particularlypointi ed out in the appended claims, it being understood that changesinthe form,proportion, size, and minor details may be` made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure l is a perspective view of the body and therunning-gear of a wagon having the present dumping mechanism appliedthereto, the wagon-body being elevated and tilted in position to dump.Fig. 2 is a central longitudinal sectional view thereof, the Wagon-bodybeing in its normal position. Fig. 3 is a similar sectional view withthe wagon-body elevated and tilted. Fig. 4 is a sectional end elevationof the rear end of the wagon.

Like characters of reference designate corresponding parts in all of thefigures of the drawings.

The present invention is especially designed for application tocoal-wagons, which may or may not be provided with chute attachments,and in the drawings l designates the frame of the running-gear of anycommon or ordinary wagon having the body 2 removably supported thereon.

In carrying out the present invention there is provided the oppositesubstantially vertically disposed elevating-standards 3, which arelocated within the opposite longitudinal sides of the running-gear frameand have their upper ends pivotally connected tothe bottom of thewagon-body by means of suitable bearing-brackets 4, so that thestandards may swing longitudinally of the wagon. The lower ends of thestandards are connected by a cross bar or rod 5, so as to maintain thestandards in a fixed mutual relation. Opposite chains or cables 6 havetheir lower ends connected to the cross-bar and their upper endsconnected to a rotatable transverse shaft 7, mounted across the lowerside of the running-gear frame and provided at one end with a` removablecrank-handle 8, located eX- teriorly of the frame and designed for themanipulation of the elevating mechanism. A suitable ratchet-wheel 9 isprovided upon one outer extremity of the shaft, and a gravitydog l0 ismounted upon the frame and in engagement with the ratchet wheel or disk,so as to prevent accidental unwinding of the chains. By this arrangementthe chains may be wou nd upon the shaft, so as to raise the oppositestandards,and thereby elevate the body of the wagon. As best indicatedin Figs. 2 and 3 of the drawings, it will be seen that the shaft :ismounted substantially midway between the opposite ends of the wagon, andthe standards are located adjacent to and in rear of the shaft.

In order that the standards may be steadied in their vertical movement,a linked connection is provided between the lower ends thereof and therear axle 1l of the' wagon. This connection is formed by means of theopposite brackets or clamps l2, suitably secured to the intermediateportion of the axle and arranged in alinement with the inner sides ofthe respective standards. A connecting-link 13 has its rear endpivotally joined to the adjacent bracket and its front end pivotallyconnected to the inner side of the adjacent standard, as at 14., at apoint just above the con necting rod or bar 5.

Rising from an intermediate point of each link there is an arm l5, whichhas its lower IOO end pivotally connected to the inner side of the link,as at 16. The upper end of the arm is provided with a cuff or sleeve 17,which is connected to the outer side thereof by means of a suitablepivotal connection 18, whereby the sleeve may rock in a verticaldirection and also longitudinally of the wagon. Each sleeve slidablyembraces the in termediate portion of the adjacent elevating-standard,so that the latter may slip through the sleeve, as the standard movesfaster than the arm, for the reason that it is farther away from the common center 19, formed by the pivotal connection between the link 13 andthe wagonaxle. By this arrangement the elevatingstandards are bracedfrom a common center both at their bottoms and their upper intermediateportions, so as to secure rigidity and stability of the elevatingmechanism.

The intermediate portion of each arm 15 is braced by means of a link 20,which has its forward end pivotally connected to the outer side of thearm, as indicated at 21, while its rear end is xedly secured to arocking or swinging bracket 22, that is pendent from the inner face ofthe adjacent side vof the running-gear frame, as indicated at 23. i

In the normal position of the wagon the elevating standards inclinedownwardly and rearwardly, whereby the connecting-links 13 assumesubstantially vertical positions pendent from the axle, while in theelevated position of the wagon bodyy the links 13 are thrown upwardlyinto substantially horizontal positions, with theother connectingelements assu ming correspondingly-elevated positions. Thus theWagon-body may be conveniently elevated and returned to its originalposition by a single operator, the mechanism being under completecontrol through the medium of the removable crank-handle, which isnormally removed, so as to obviate unnecessary projections in the normalconditionof the wagon.

It will be understood that the" rear end of the wagon-body has a pivotalconnection with the runninggear frame in order that the front end of thebody may be elevated to give the body a rearwardly and downwardlyinclined tilt for sliding or shooting the contents ofthe wagon-bodyoutwardly through the rear vend thereof.

In some instances it is necessary o'r desirable to slightly elevate thepivotally-mounted rear end of the body after the opposite front end hasbeen swung upwardly, so that the discharging contents thereof may beproperly directed to an opening in a pavement orthe like, and thereforeI have provided an adjustable pivotal connection between the rear end ofthe body and the running-gear, comprising a rock-shaft 24, which is bestshown ried by said frame.

ing and is provided with a terminal fixed crank-arm 26, which normallyinclines downwardly and forwardly. To the outer free end of thiscrank-arm there is pivotally connected an upstanding link 27, which hasits upper free end pivotally connected to the adjacent rear portion ofthe wagon-bdy, as indicated at 28. By rocking the shaft, so as to throwthe opposite crank-arms upwardly, the corresponding links Will also beelevated, thereby raising the rear end of the wagon-body.

For convenience in manipulating the rockshaft there is provided anoperating lever or crank 29, one for each end portion of the shaft, soas to be accessible from either side ofthe wagon. Each lever has `aninner terminal angular opening 30, as best shown in Fig. 2 of thedrawings, which normally and loosely embraces the intermediate portionof the shaft, so as to hang downwardly, and

thereby prevent an unnecessary projection at the rear end of the wagon.To operatively connect the lever to the shaft, the latter is proyidedwith an angular' enlargement or head 31 next to the inner side of theadjacent bearing 25 and upon which the angular opening of the lever isvdesigned to be slid, thereby [ixedly connecting the lever and the shaftfor operation by the former.

To hold the rear end 'of the wagon-body at any elevated adjustment,there is provided a pendent rack 32 for adj ustable engagement with thelever, so as to hold the rock-shaft stationary, and thereby secure theWagonbody at any elevated adjustment. This rack is preferably formed byan arm pendent from the adjacent bearing 25 and is provided with avertical series of perforations 33. The lever has a longitudinal slot34, and this slotted portion passes across the inner face of theperforate arm, so that a locking pin or key 35 may be inserted throughone of the perforations and the slot in the lever, thereby locking thelatter and the rock-shaft against accidentalmotion. To prevent loss ofthe pin, it is connected to the running-gear frame by means of a chainor other flexible connection 36.

From the foregoing description it is apparent that the present form ofelevating mechanism may be applied to any ordinary wagon withoutaltering or changing the latter, and the device may be convenientlymanipulated Without requiring any particular skill or experience.

It is particularly desired to call attention to the fact that the rearpivotally-mounted end of the wagon-bodyremains relatively fixed in itssubstantially normal position upon the running-gear during the upwardswing or elevation of the front end of the body, and said pivotal endofthe body is adjustably elevated from its normal position upon therunning-gear after the front end of the body has been swung upwardly, soas to adjust the inclination of the body for facilitating the connectionof a chute attachment or for any IOO IIO

other purpose. Thus there are two distinct steps in the adjustment ofthe body-first, the swinging upwardly of the front end of the body uponthe pivotal mounting of the rear end thereof as a center, and,second,the adjustable elevation of the pivotally-supported rear end ofthe body after the first step has been taken. Moreover, as therock-shaft is normally free to turn and the link is pivotally connectedto the crank-arm the pivotal connection 28 between the upper end of thelink and the wagon-body is arranged to slide in opposite directions withthe body, so that the latter, or rather the pivotal connection of thelatter, may automatically accommodate itself tothe upward swing of thefront end of the body.
